This fix is in response to test results reported by Jerry Needell
	<jerry.needell@unh.edu> for the SPARC/ERC32 and tracked as PR80.
	* include/bsp.h: TM27 was not running properly because the ERC32
	and LEON cannot nest interrupts at the same level.  The BSP test support
	had to be modified to support using two different interrupt sources.
